Answer:
Step-by-step explanation:
Let's denote the time that Adrian traveled on the bike at 13 mph by "t" and the time that he walked at 3 mph by "9 - t" (since the total trip took 9 hours).
Since we know that the total distance traveled was 87 miles, we can write the equation:
distance traveled on bike + distance traveled walking = 87
Using the formula distance = rate x time, we can express the distance traveled on the bike and walking in terms of time:
13t + 3(9 - t) = 87
Simplifying this equation:
13t + 27 - 3t = 87
10t = 60
t = 6
Therefore, Adrian traveled on the bike for 6 hours (at 13 mph) and walked for 3 hours (at 3 mph).

Mailani saves some money in a box under her bed. She deposits an additional amount into a savings account where it earns interest compounded annually. This situation can be modeled by the function . Which statement is true? Select all that apply.
The correct statements are:
Mailani saves $200 in a box under her bed.The y-intercept of the function is (0, 700).Explanation:
The function f(x) represents the total amount of money that Mailani has saved after x years. The first term 500 represents the initial amount she saved in the box under her bed, and the second term (1+0.04)^x represents the amount she deposited into the savings account, which earns an interest rate of 4% compounded annually. The third term +200 represents the additional amount she deposited every year into the savings account.
The range of the function is y>=500, since the initial amount saved is 500, and the function is increasing with time.The y-intercept of the function is (0, 700), not (0, 200), because the initial amount saved in the box is 500, and the additional amount deposited into the savings account is 200 per year, so after 0 years, the total saved amount is 500+200=700.The function does not have an asymptote at y=200. An asymptote is a line that a graph approaches but never touches. In this case, the function is increasing with time, so it does not approach any line as x gets larger.Learn more about asymptote here brainly.com/question/4084552

(b) During a housing boom the price of houses increased over an 18 month period. A house that cost 240000 at the start of the period had a sale value of 276000 at the end of the period. What was the average rate of change in the price per month?
After answering the presented question, we can conclude that As a result, the average monthly rate of change in price during the housing bubble was $2,000.
What is average rate?The term "average rate" can have different meanings depending on the context in which it is used. In general, it refers to the amount of change that occurs over a certain period of time, divided by the length of that time period. Here are a few examples of how the term might be used in different fields.
The average monthly rate of change in price can be estimated by dividing the total price change by the number of months:
(final price - beginning price) / number of months = average rate of change
The beginning price was $240,000, the final price was $276,000, and the time duration was 18 months in this example. Hence, using these data, we can calculate the average rate of change as:
(276000 - 240000) / 18 = 36000 / 18 = 2000 Average rate of change
As a result, the average monthly rate of change in price during the housing bubble was $2,000.

Use the slope of 5/3 and the point (−3, –4) to graph the line
The equation of the line is 3y-5x=3 and the graph is attached.
Geometrically speaking, a line is a one-dimensional figure because it has length but no width. A group of points can be extended endlessly in opposing directions to form a line. Two points in a two-dimensional plane determine it. There are, however, additional ways to formulate the equation of a line in a two-dimensional coordinate system. The three most popular methods are the point-slope form, slope-intercept form, and general or standard form of the equation of a line. As its name suggests, the point-slope form combines a line point and a straight-line slope. The equations of infinite lines with a particular slope can be expressed, however when we specify that the line passes through a particular point, we get a singularity.

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Hudson sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
80 visitors purchased no costume.
32 visitors purchased exactly one costume.
3 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase more than one costume as a percent to the nearest whole number.
The probability that the next person will purchase more than one costume as a percent to the nearest whole number is 3%
.Out of the total 80 + 32 + 3 = 115 visitors, 80 did not purchase any costumes and 32 purchased exactly one costume. This means that the remaining 3 visitors purchased more than one costume.
Therefore, the probability that the next person will purchase more than one costume is 3/115, which is approximately 0.0261.
To express this as a percentage to the nearest whole number, we need to multiply by 100 and round to the nearest integer. Thus, the answer is:

A camera's normal price is $460. Buying it duty free reduces the price by 25%. Find the actual selling price of the camera.
The actual selling price of the camera after the 25% discount is $345.
What is selling price?The amount received by the buyer is the selling price of a product or service. Although the seller sets the price, a number of variables affect how the seller arrives at that particular figure. Depending on the seller's discretion, different customers may pay different prices for the same good or service.
If the normal price of the camera is $460, a 25% reduction in price would be:
25% of $460 = 0.25 x $460 = $115
This means the reduction in price when buying the camera duty-free is $115.
So the actual selling price of the camera after the discount is:
$460 - $115 = $345
Therefore, the actual selling price of the camera after the 25% discount is $345.

The quadratic function's equation, when given the numbers in the table, can be found to be f(x) = x^2 - 5x + 6.
How to find the quadratic function's equation ?We are given a table of values and need to find the quadratic function in standard form: f(x) = ax^2 + bx + c. Let's use the points (-6, 72), (-4, 42), and (-3, 30).
For point (-6, 72):
72 = a(-6)^2 + b(-6) + c
For point (-4, 42):
42 = a(-4)^2 + b(-4) + c
For point (-3, 30):
30 = a(-3)^2 + b(-3) + c
Let's use the elimination method.
1 - 3) 42 = 27a - 3b
2 - 3) 12 = 7a - b
b = 7a - 12
Substitute this expression for b into the first equation:
42 = 27a - 3(7a - 12)
42 = 27a - 21a + 36
6 = 6a
a = 1
Now that we know a = 1, let's find b:
b = 7(1) - 12
b = -5
Finally, let's find c by substituting a and b into any of the original equations. We'll use the first one:
72 = 36(1) - 6(-5) + c
72 = 36 + 30 + c
6 = c

Fond the sum 2/5 + 3/6
To add 2/5 and 3/6, we need to find a common denominator for the two fractions. The smallest number that both 5 and 6 divide into evenly is 30. So, we can convert the two fractions to have a denominator of 30:
2/5 = 12/30 3/6 = 15/30
Now, we can add the two fractions by simply adding their numerators (since they have the same denominator):
12/30 + 15/30 = 27/30
We can simplify the fraction by reducing it to the lowest terms. Both the numerator and denominator have 3 as a factor, so we can divide them both by 3:
27/30 = (3 x 9) / (3 x 10) = 9/10
Therefore, the sum 2/5 + 3/6 is equal to 9/10.

we have bi =0 whenever i is odd. Prove that P(F )=W1 ⊕ W2 .

What is a polynomial?
a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
To prove that P(F) is the direct sum of W1 and W2, we need to show two things: first, that every polynomial in P(F) can be written as a sum of a polynomial in W1 and a polynomial in W2, and second, that this decomposition is unique.
Let's begin by showing that P(F) can be written as the direct sum of W1 and W2. Consider an arbitrary polynomial f(x) in P(F). We can write it as a sum of even and odd terms as follows:
f(x) = [f(x) + f(-x)]/2 + [f(x) - f(-x)]/2
The first term on the right-hand side is even, while the second term is odd. Let's define g(x) = [f(x) - f(-x)]/2 and h(x) = [f(x) + f(-x)]/2. Note that g(x) is odd and h(x) is even. Thus, we have expressed f(x) as a sum of an even polynomial h(x) and an odd polynomial g(x).
To show that this decomposition is unique, suppose that f(x) can be written in two ways as a sum of an even polynomial and an odd polynomial:
f(x) = h1(x) + g1(x) = h2(x) + g2(x)
where h1(x) and h2(x) are even polynomials, and g1(x) and g2(x) are odd polynomials. Then we have:
[h1(x) - h2(x)] = [g2(x) - g1(x)]
Since h1(x) - h2(x) is even, and g2(x) - g1(x) is odd, we have:
[h1(x) - h2(x)] = 0 and [g2(x) - g1(x)] = 0
This implies that h1(x) = h2(x) and g1(x) = g2(x), so the decomposition is unique.
Therefore, we have shown that P(F) is the direct sum of W1 and W2.

A TV cable company has 9600 subscribers who are each paying $36 per month. It can get 160 more subscribers for each $0.50 decrease in the monthly fee. What rate will yield maximum revenue, and what will this revenue be?
The function has the maximum revenue of $348,480 with the increasing rate of $33.
Explain about the maxima of function:The highest and smallest values of a function, respectively, can either be found inside a specific range or distributed throughout the entire domain. They are also sometimes referred to collectively as the function's extrema. The plural forms of a function's maximum and minimum are called maxima and minima, accordingly.
Given data:
We are aware that monthly subscription fees are $36.The corporation can increase its subscription count for a $0.50 drop.We also know that the business has 9600 subscribers and has the capacity to add 160 more.The overall revenue is thus:
y = (36 - 0.50x)(9600 + 160x)
Differentiate with respect to x.
y ' = (-0.50)(9600 + 160x) + 160(36 - 0.50x)
y' = -4800 - 80x + 5760 - 80x
y' = 960 - 160x
To find x, put y' = 0
960 - 160x = 0
x = 960/160 = 6 (critical point)
Function is decreasing in interval - [6, +∞)
Increasing Function in interval - (-∞, 6]
Thus, the function has the maximum value at x = 6.
maximum revenue f(6):
f(6) = (36 - 0.50x)(9600 + 160x)
f(6) = (36 - 0.50(6))(9600 + 160(6))
f(6) = $348,480
Rate : 36 - 0.50(6) = $33

The assertion is accurate. This mean option that is selected should be true
The formula c = √(a 2 + b 2), where a and b are the lengths of the semi-major and semi-minor axes, respectively, yields the foci of a hyperbola.
What exactly is hyperbola?. A hyperbola is a particular kind of conic section that resembles two slightly mirrored parabolic curves. It is described as the collection of all points in a plane where the difference between the locations of two fixed points (referred to as foci) is always constant.
Each of the two branches of a hyperbola resembles a parabola. In relation to the hyperbola's centre, the branches are symmetric. The semi-major axis is the distance between the centre and each vertex, whereas the semi-minor axis is the distance between the centre and each terminal of the transverse axis.
When a² = 25 and b² = 9,
the hyperbola (x-1)2/25 - (y+3)2/9=1 can be calculated.
In light of this, c = √(25 + 9) = √ (34).
The hyperbola's center is located at (1, -3).
The foci are at (1 + √(34), -3) and (1 - √(34), -3), respectively.

The net shown represents a square pyramid. 20 ft 32 ft • Determine the area, in square feet, of one triangular face of the square pyramid • Determine the total surface area, in square feet, of the square pyramid.
The total surface area must be calculated by adding the areas of all five faces, the four triangular faces, and the square base.
What is a square pyramid known as?The term "square pyramid" refers to a three-dimensional geometric form with a square base and four triangular faces or sides that meet at a single point (known as a vertex). Because it has five faces, it is referred to as a pentahedron.
Given :
Let s represent the square base's side length and h represent the slant height of each triangle face. The area of a single triangle is then determined by:
A = (1/2) * s * h
The areas of all five face the four triangular faces and the square base must be added up in order to determine the overall surface area of the pyramid.
The overall surface area is: since the square base has a simple area of s2.
When we replace A with the expression, we obtain:
We require further details regarding the pyramid in order to determine the values of s and h.

Answer:
168°------------------------------
Supplementary angles add up to 180°:
m∠A + m∠B = 180°Substitute and solve for x:
x - 9 + 7x + 21 = 1808x + 12 = 1808x = 168x = 21Find the measure of ∠B:
m∠B = (7*21 + 21)° = 168°How do I find the value for f(x)=6+3x
Answer: To find the value of f(x) for a given value of x, you need to substitute that value of x into the equation and simplify.
For example, if you want to find f(2), you would substitute x=2 into the equation:
f(x) = 6 + 3x
f(2) = 6 + 3(2)
f(2) = 6 + 6
f(2) = 12
Therefore, f(2) = 12.
Step-by-step explanation:
The value of f(x) is 18 given that the value of x is substituted as 4. The expression is usually solved with substitution method.
How to solve the expression?To find the value of f(x) for a given value of x, you need to substitute that value of x into the equation for f(x) and solve for f(x).
For example, if you want to find the value of f(x) when x = 4, you would substitute x = 4 into the equation for f(x) as follows:
f(4) = 6 + 3(4)
Simplifying the expression on the right-hand side:
f(4) = 6 + 12
f(4) = 18
Therefore, the value of f(x) when x = 4 is 18.

Hope this helps!
Step-by-step explanation:
(x−a)xa3+(x−a)x−13a2+(x−a)x−23a+(x−a)31=(x−a)xx3
The solutions to the equation are x = a and x = a/2.
Equation calculation.
We can simplify the left-hand side of the equation using the common denominator of x^3:
(x-a)x/x^3 + (x-a)(-1)/(3a^2 x^3) + (x-a)(-2)/(3a x^3) + (x-a)(1)/(x^3)
= [(x-a)x^2 - (x-a)/(3a^2) - 2(x-a)/(3a) + (x-a)x]/x^3
= [(x^3 - a^3)/x^2 - (1/(3a^2))(x-a) - (2/(3a))(x-a)]/x
= [(x^2 + ax + a^2)(x-a)/(x^2 a^2) - (x-a)/(3a^2) - (2/3)(x-a)/a]/x
= (x^2 + ax + a^2)/(x^2 a^2) - 1/(3a^2) - 2/(3a)/x
= (3x^2 + 3ax + 3a^2 - x^2 a - ax^2 - a^3)/(3a^2 x^2)/x
= (2x^2 + 3ax + 3a^2 - ax^2 - a^3)/(3a^2 x^2)/x
= (x^2 + 3ax + 3a^2 - a^3)/(3a^2 x^2)/x
Now, we can see that the expression on the right-hand side is:
(x-a)/(x^3)
Multiplying both sides by x^3, we get:
(x-a)x = (x^2 + 3ax + 3a^2 - a^3)/3a^2
Multiplying both sides by 3a^2, we get:
(x-a)3a^2x = x^2 + 3ax + 3a^2 - a^3
Expanding (x-a)(3a^2)x, we get:
3a^2x^2 - 3a^3x = x^2 + 3ax + 3a^2 - a^3
Moving all terms to one side, we get:
2x^2 - 3ax + 2a^2 = 0
This is a quadratic equation, and we can solve for x using the quadratic formula:
x = [3a ± sqrt((9a^2 - 8a^2)/4)]/4
x = [3a ± a]/4
x = a or x = 2a/4 = a/2
Therefore, the solutions to the equation are x = a and x = a/2.
